Objective: To study the effect of early intervention on psychosocial development of children in single child family. Method:30 babies were enrolled as intervention group from they were fetus. Another 37 were enrolled as control group. The former received intervention under the Guide of Different Stages from 0 to 6 years old. Achenbach Children Behavior Checklist (CBCL) and Binet Intelligent Test were used to assess the results.Results:The rate of behavior group was 6.7%, significantly lower than that of the control group (13.5%) and Chinese norm (14.2%). The average IQ of the intervention group was significantly higher than control. But there was no significant difference in Social Adaptability between the two groups. Conclusion:Early education and intervention can improve psychosocial development children in single child family.

Objective To explore the medium effect of social support in process of attachment styles and coping styles on criminal juveniles and adolescents with mood disorders.Methods The survey used in the research included Experiences of Close Relationships Inventory (ECR),Social Support Revalued Scale(SSRS) and Coping Style Questionnaire(CSQ) conducted by three groups:177 criminal juveniles,80 adolescents with mood disorders and 163 normal teenagers.Results Firstly,there were significant differences in the avoidant attachment,attachment anxiety,objective support,subjective support,utilization of support,solving problem,rationalization,self-accusation and retreat among three groups (F=7.902,8.047,59.009,19.248,5.304,7.596,10.652,6.699,11.009;P＜0.05).Secondly,attachment avoidance had significant negative correlation with both utilization of support and help seeking behaviors in the group of mood disorders (r =-0.470,-0.350; P＜ 0.01).Similarly,avoidant attachment had significant negative correlation with both subjective support and utilization of support respectively (r=-0.232,-0.235 ; P＜0.01) in the group of criminal juveniles.The subjective support had significant positive correlation with solving problem (r=0.272,P＜0.01) and as well as the utilization of support with both solving problem and help seeking behaviors (r=0.258,0.424; P＜ 0.01).Attachment anxiety had significant negative correlation with objective support and had significant positive correlation with self-accusation respectively (r=-0.253,0.300;P＜0.01).Finally,utilization of support as a medium completely effect on the process of avoidant attachment and help seeking behaviors in the group of mood disorder and criminal juveniles.Moreover,subjective support and utilization of support as medium both affected a part in the process of avoidant attachment and solving problem for the group of criminal juveniles.Conclusion First,both adolescents with mood disorders and criminal juveniles have unsafe attachment mode,which are lacked social support and easy to take negative coping styles.Yet,the level of attachment avoidance and subjective support of criminal juveniles was found different compared to teenagers with mood disorder.Second,the attachment styles for both adolescents with mood disorders and criminal juveniles have impact on coping styles by the means of social support,but there were slightly different way.

The chemical structures of mequindox related metabolites in chicken plasma had been investigated using high performance liquid chromatography combined with linear ion trap quadrupole(LC-ESI/LTQ) and high performance liquid chromatography combined with ion trap-time of flight-mass spectrometry (LC-ESI/IT-TOF).Samples were separated by Hypersil BDS C_(18) and symmetry Shield columns, respectively, and 0.01% formic acid aqueous(A) and methanol(B) were used as mobile phase with gradient elution.Electros pray ionization mass spectrometric(ESI) source was used and operated in positive ion mode.When chickens were orally administered with mequindox at dosage of 20 mg/kg, blood samples were collected from the brachi al vein.Mequindox and its metabolites were extracted by the mixture of acetonitrile and acetoacetate (3:2, V/V).After solvent evaporated, the residue was dissolved in 30% methanol aqueous and the solution was detected by LC/IT-TOF MS and LC-ESI/LTQ.The molecule weight from LC-ESI/IT-TOF was analyzed by software Shimadzu's Composition and the mass chromatogram from LC-ESI/LTQ was analyzed by software Xcalibur 2.0.7.According to the molecular weight and MS~n data, referring the metabolic reaction rules, five chemical structures of mequindox related metabolites in chicken plasma were identified.Metabolites (M1-M4) were synthesized to verify the structure of metabolites.The metabolites are 3-methyl-2-(1-hydroxy) ethyl-qui-noxaline-N~1,N~4-dioxide(Ml), 3-methyl-2-(1-hydroxy) ethyl-quinoxaline-N~4-oxide(M2), 3-methyl-2-acetyl-quinoxaline-N~4-oxide, 3-methyl-2-acetyl-quinoxaline (M4), 3-hydroxymethyl-2-(1-hydroxy) ethyl-quinoxa-line-N~1,N~4-dioxide (M5).

Chloroquines are the long-established prescription drug, which are often used clinically to treat malaria and connective tissue diseases. Since December 2019, corona virus disease 2019 （COVID-19） outbreaks caused by 2019 novel coronavirus （2019-nCoV） has occurred in China and many countries around the world. Due to the lack of drugs against COVID-19, the disease spreads rapidly and the mortality rate is relatively high. Therefore, specific drugs against 2019-nCoV need to be quickly screened. The antimalarial drug chloroquine phosphate which has already been approved is confirmed to have an anti-2019-nCoV effect and has been included in diagnostic and therapeutic guidelines. However, awareness of the risk of chloroquine phosphate causing acute poisoning or even death should be strengthened. The current dosage recommended in clinical treatment is larger than that in previous treatment of malaria and the period of treatment is longer. Many provinces have required close clinical monitoring of adverse reactions. This paper reviews the pharmacological effects, poisoning and toxicological mechanisms, in vivo metabolism and distribution, and forensic issues of chloroquine drugs, in order to provide help to forensic practice and clinical work.

Objective: To examine the effects of parental rearing style and its consistency on sleep problems of preschool children and to provide theoretical basis for making early family intervention measures. Methods: A questionnaire survey was conducted among 2 744 children and their parents in 19 kindergartens in Anqing city. Parental Behavior Inventory (PBI) was used to investigate the rearing style of parents, and Chinese version of Children s Sleep Habit Questionnaire (CSHQ) was used to evaluate the incidence of sleep among preschoolers. Results: Preschool children s overall rate of sleep disorder was 15.5%, and accompanied by sleep duration disorder (70.0%), sleep resistance (64.2%), sleep latency (38.7%), anxiety (15.5%), daytime sleepiness ( 10.1 %). Living in urban areas, parents smoking and drinking behaviors, and parents parenting style all affected preschoolers sleep ( P <0.05). Multivariate Logistic regression analysis showed that fathers active rearing style was negatively correlated with preschool children s sleep problems such as delayed sleep impedance and short sleep duration, while mothers active rearing style was negatively correlated with preschool children s sleep problems such as sleep resistance and night wake up ( P <0.05). There was a positive correlation between father s severe rearing style and preschoolers sleep resistance, sleep duration, short sleep disordered breathing, daytime sleepiness and total sleep problems, and mother s severe rearing style and preschoolers sleep duration, short sleep anxiety, night wakefulness, daytime sleepiness and total sleep problems ( P <0.05). Consistent rate of negative rearing patterns was a risk factor for short sleep duration in preschoolers ( OR =2.19，95% CI =1.12-4.28， P =0.02). Conclusion The detection rate of sleep problems in preschoolers is high. Parental supportive involvement has a positive effect on preschoolers sleep, while parental coercion hostile parenting has a negative effect on preschoolers sleep. The consistent rate of rearing styles affects the sleep duration of preschoolers.

Objective To evaluate the role of interleukin-5 (IL-5) in the pathogenesis of allergic asthma, we observed the effects of recombinant human (rh) IL-5 inhalation on changes of activity and number of circulating eosinophils in allergic asthmatics, as well as concentrations of serum IgE.Methods A randomized double-blind, placebo-controlled study design was employed in each subject which acted as his or her own control. Eight nonsmoking asthmatics were enrolled in this study. All paients had mild atopic asthma, with baseline forced expiratory volume in 1 second (FEV1) greater than 70% of predicted value, requiring only intermittent use inhaled β2-agonists. Each paitent had one or more documented positive skin prick test responses to aeroallergens. None had received inhaled or oral corticoseroids in the previous 3 months. Each subject inhaled 10 μg of rhIL-5 (Genzyme Co., Boston, MA) in vehicle (0.1% bovine serum albumin in 0.9% saline) or vehicle only as a 0.5 ml nebulized solution. At least 4 weeks were allowed to elapse between the two inhalation, and the order of inhalation of rhIL-5 or vehicle was randomized. Measurements of total nuclear blood cell counts and cell differntial counts, and concentrations of eosinophil cationic protein (ECP) were performed before, and at 2, 24, and 48 h after the inhalation of rhIL-5 or vehicle. Levels of ECP in serum were determined with commercially available ECP Fluoroimmunoassay kits (Pharmacia AB, Uppsals, Sweden) according to the procedures recommended by the manufactures. All data were presented as mean±standard error of mean. Statistical analysis was done by repeated measures analysis of variance (ANOVA) for data conforming to a normal distribution, and by Friedman's test for those data with a nonparametric distribution.Results Eosinophil numbers and ECP levels within the control group did not appear to change from baseline at any time throughout the study. Eosinophil numbers from baseline (3.6±1.1×105/ml) to 6.3±1.2×105/ml (P<0.01) at 24 h, and to 5.7±0.9×105/ml (P<0.01) at 48 h after IL-5 inhalation. Accompanying this significant blood eosinophilia was a significant elevation of serum ECP levels. Compared with baseline value (6.3±1.1 pg/ml), inhalation of IL-5 lead to ECP levels in crease with time, reaching a significant hight extent at 24 h (17.6±2.8 pg/ml, P<0.01); And this elevated ECP levels lasted at least 48 h (18.1±2.9 pg/ml, P<0.01). However, IL-5 inhalation had no significant effect of levels of serum total IgE.Conclusions The findings in the present study provided direct evidence the IL-5 not only induced a significant blood eosinophilia, but also resulted in the activation of circulating eosinophils. Our data further support the importance of IL-5 in the pathogenesis of brochial asthma in human.

Objective:To explore the correlation between attempted suicide and childhood trauma as well as inflammatory cytokines levels in adolescents with depressive disorder.Methods:From January to December 2021, a total of 164 adolescents with depressive disorder were included and categorized into attempted suicide group ( n=108) and non-attempted suicide group ( n=56) according to whether they accompanied attempted suicide or not. The Chinese version of the suicide module of MINI 5.0, the childhood trauma questionnaire(CTQ), and the center for epidemiological studies depression scale (CES-D) were used to assess suicidal behavior, childhood trauma and depressive symptoms, while the plasma inflammatory cytokines levels were measured by electrochemiluminescence technology. The data were statistically analyzed by SPSS 23.0 software. Logistic regression was applied to analyze the independent influencing factors of attempted suicide and the predictive value of each independent risk factor for attempted suicide was assessed by receiver operating characteristic curve(ROC) curves. Results:The prevalence of attempted suicide was 65.9%(108/164) in adolescents with depressive disorder.The univariate analyses showed that the total CTQ score ((55.19±12.44), (45.50±12.11)) ( t=-4.771, P<0.001), CES-D total score ((40.75±10.26), (32.98±13.39)) ( t=-4.131, P<0.001), IL-6 level(1.87 (1.32, 2.69) pg/mL, 1.56 (1.05, 1.87) pg/mL)( Z=-3.102, P=0.002), IL-10 level (0.53 (0.38, 0.83) pg/mL, 0.47 (0.31, 0.69) pg/mL) ( Z=-2.100, P=0.036) and IL-17A level (2.20 (1.52, 3.65) pg/mL, 1.67 (1.25, 2.97) pg/mL) ( Z=-2.254, P=0.024) in plasma of patients in the attempted suicide group were significantly higher than those in non-attempted suicide group. Logistic stepwise regression analyses showed that CTQ total score, IL-6, IL-10, and IL-17A were risk factors for attempted suicide in adolescents with depressive disorder.The ROC showed that the total score of CTQ combined with IL-6 (AUC=0.782, 95% CI=0.709-0.855, P<0.001), the total score of CTQ combined with IL-10 (AUC=0.765, 95% CI=0.688-0.841, P<0.001), and the total score of CTQ combined with IL-17A (AUC=0.762, 95% CI=0.684-0.840, P<0.001) had a larger area under the curve, indicating better recognition and prediction ability for attempted suicide, with high sensitivity and specificity. Conclusion:The incidence of attempted suicide in adolescents with depressive disorder is high, and which is closely related to childhood trauma and the levels of inflammatory cytokines.

The prevalence rate of tic disorder in Chinese children and adolescents is relatively high, and tic disorder is often co-occurring with psychiatric disorders such as attention deficit and hyperactive disorder and obsessive compulsive disorder.The cognitive impairments of tic disorder patients with different clinical types, course of disease and comorbidities are different, but all affect the learning and life quality of patients.Exploration of the cognitive function characteristics of tic disorder patients is conducive to further understanding of the disease and its etiological mechanism, and has guiding significance for clinical recognition, diagnosis and treatment.

Objective: Excessive daytime sleepiness (EDS) and insomnia symptoms are common in patients with major depressive disorder (MDD), which might lead to a poor prognosis and an increased risk of depression relapse. The current study aimed to investigate the prevalence, and sociodemographic and clinical correlates of EDS and insomnia symptoms among adolescents with MDD. Methods: The sample of this cross-sectional study included 297 adolescents (mean age=15.26 years; range=12–18 years; 218 females) with MDD recruited from three general and four psychiatric hospitals in five cities (Hefei, Bengbu, Fuyang, Suzhou, and Ma’anshan) in Anhui Province, China between January and August, 2021. EDS and insomnia symptoms, and clinical severity of depressive symptoms were assessed using Epworth sleepiness scale, Insomnia Severity Index, and Clinical Global Impression-Severity. Results: The prevalence of EDS and insomnia symptoms in adolescents with MDD was 39.7% and 38.0%, respectively. Binary logistic regression analyses showed that EDS symptoms were significantly associated with higher body mass index (odds ratio [OR]=1.097, 95% confidence interval [CI]=1.027–1.172), more severe depressive symptoms (OR=1.313, 95% CI=1.028–1.679), and selective serotonin reuptake inhibitors use (OR=2.078, 95% CI=1.199–3.601). And insomnia symptoms were positively associated with female sex (OR=1.955, 95% CI=1.052–3.633), suicide attempts (OR=1.765, 95% CI=1.037–3.005), more severe depressive symptoms (OR=2.031, 95% CI=1.523–2.709), and negatively associated with antipsychotics use (OR=0.433, 95% CI=0.196–0.952). Conclusion EDS and insomnia symptoms are common among adolescents with MDD. Considering their negative effects on the clinical prognosis, regular screening and clinical managements should be developed for this patient population.

ObjectiveTo investigate the status of sleep insufficiency in children and adolescents with mental disorders and related influencing factors. MethodsA total of 131 children and adolescents who were admitted to the Third People's Hospital of Fuyang from February to June 2021 and met the diagnostic criteria of International Classification of Diseases， tenth edition （ICD-10） for schizophrenia， depression or childhood-onset mood disorders were selected as the research subjects. A self-compiled questionnaire was used to collect the general demographic information， sleep status， lifestyle habits， family and school status of the selected individuals. The demographic information was compared between sleep sufficiency group and sleep insufficiency group. Spearman rank correlation was used to screen the influencing factors. Results① Among 131 children and adolescents with mental disorders， 93 cases （71.0%） had sleep insufficiency. There were significant differences between sleep insufficiency group and sleep sufficiency group in terms of disease types （χ²=8.798， P=0.012）， experience of being beaten in recent 6 months （χ²=3.427， P=0.035）， being scolded in recent 6 months （χ²=4.145， P=0.031）， and cyberbullying over the past year （χ²=4.187， P=0.041）. ② Among patients with sleep insufficiency， 77 cases （82.8%） reported difficulty in falling asleep and 69 cases （74.2%） reported nocturnal awakenings. ③ Sleep insufficiency in children and adolescents with mental disorders was positively correlated with the experience of being scolded （r=0.210， P=0.037） or beaten （r=0.145， P=0.023） over the past 6 months and cyberbullying over the past year （r=0.179， P=0.041）. ConclusionChildren and adolescents with mental disorders suffer a high risk of sleep insufficiency， and is closely associated with depressive disorder， experience of being scolded or beaten over the past 6 months， and cyberbullying over the past year.
